Groundwater chemical quality studies were carried out in upper Manimuktha sub basin, Vellar, South India. Fifty two groundwater samples were collected from dug and bore well during pre and post monsoon seasons of 2006. The samples were analyzed for various water quality parameters such as pH, Electric Conductivity, Total dissolved solids, Calcium, Magnesium, Sodium, Potassium, Bicarbonate, Carbonate, Sulphate and Chloride. The results were evaluated in detail and compared with WHO water quality standards. An overall assessment of the water samples indicated that the physico and chemical parameters are lies within the permissible limit except in some locations. It is inferred from Piper trilinear diagram that the water is mostly of alkaline earth exceeds alkalies. Gibbs diagram reveals that the overall hydrogeochemical environment of the study area is controlled by the rock water interaction dominance. According to the USSL classification of water quality, it falls under C3 - S1 category. These results were taken in to GIS platform for further processing to understand the spatial variation. Finally, the quality variation is brought out at village level.Keywords

Sustainable development will require replacement of older technologies and increased use of both renewable energy and wireless technology. What if there was a way we could harvest the energy that is being transmitted and use it as a source of power for handhelds? And also that to from Non-conventional energy source like solar power. This paper deals with a system that enables you to charge your handhelds wirelessly form zero pollutant solar energy. A system that to presented will be using a receiving antenna and charge pump technology to charge a handhelds battery without wires. The base station which is a transmitter of power is powered from solar energy. The solar energy which is trapped is transmitted as radio frequency from the base station. At the receiving end we contain antenna that is tuned to transmitted frequency and a charge pump to charge up the battery of Handhelds.Keywords

In the present paper deals with the study of hydrogeochemistry of groundwater by multivariate statistical techniques such as factor and cluster analyses. The upper Thirumanimuthar sub-basin, Cauvery River, hard rock terrain in Salem District covering an area of about 346.40 km2 has been selected for the study. Fifty one samples were collected during premonsoon season 2007 and analysed for various water quality parameters like pH, EC, TDS, Ca, Mg, Na, K, HCO3, CO3, SO4, Cl and TH. Hydrogeochemical data of 51 groundwater samples were subjected to Q- and R- mode factor and cluster analysis. R-mode analysis reveals the interrelations among the variables studied and the Q-mode analysis reveals the interrelations among the samples studied. The R-mode factor analysis shows that Na and CI with HCO3 account for most of the electrical conductivity and total dissolved solids of the groundwater. The 'single dominance' nature of the majority of the factors in the R-mode analysis indicates non-mixing or partial mixing of different types of groundwaters. Both Q-mode factor and R-mode cluster analyses show that there is an exchange between the river water and adjacent groundwater. Cluster classification map reveals that 97.79% of the study area comes under cluster I classification.Keywords

An attempt has been made to demarcate sites for groundwater irrigation quality at upper Manimuktha sub basin, Velar basin, Tamil Nadu through GIS technique using ARC/GIS Software. The irrigation quality standard output was taken to GIS platform. The work was executed with the weighted rating analysis in GIS environment. Spatial and non-spatial data were assessed in a quick and efficient way in GIS. The term 'geographic' in GIS refers to the locational attributes which define the spatial positioning of the piece of information on the face of the earth. The advent of digital computers, with high data processing speed and the development of analytical tools in GIS to handle geographically referenced data with ease and flexibility, computer aided GIS has become a reality of late. Using of GIS in hydrogeology is only at its beginning, but there have been successful applications that started to develop. The favourabilty of the irrigational quality was demarcated in GIS. The favourable area occupying in premonsoon was 269 km2 and in the postmonsoon 239 km2.Keywords

Monitoring of blood glucose levels is clinically crucial in managing diseases affecting insulin secretion and resistance, most notably diabetes mellitus and cystic fibrosis. Blood glucose s used to monitor the amount of glucose in the blood, especially patients with symptoms with the abnormally of high or low blood glucose levels. Most recently, they enable diabetic patients to administer appropriate insulin doses to human health. The availability of in-house glucometers, as opposed to clinical-use equipment, has dramatically improved the quality of life of diabetic’s patient. However, such monitors require a blood draw through finger pricks for each test, which causes pain and inconvenience. Each test also needs a new test-strip, contributing to the recurring cost of such a device. Typically the blood glucose monitoring is the non-invasive technique which may cause distress and discomfort, particularly in the pediatric patient. We introduce an architecture that uses Near Infrared (NIR) spectroscopy to determine blood glucose levels based on transmittance spectroscopy on the nose lobe. The Measurement of glucose in the respiratory fluid by a collection of exhaled breath in condensate and therefore, a potentially clinically useful method of estimating blood glucose levels identified and therefore it is the excellent agreement between these diabetics blood glucose level.Keywords

In this study, melanoma was detected at an early stage using modified CAT optimization algorithm (MCOA) based on non-convex boundary edge extraction, pixel size, shape and intensity variations on the skin. MCOA can detect skin cancer at an early stage by extracting the non-convex border of the affected region prevent cancer spread. Thus melanoma is curable when detected at an early stage. MCOA extracts image features and obtains non-convex boundaries of melanoma in the skin image. The non-convex boundary region leads to visualization of discriminative features of melanoma based on the region of interest and scaling. The proposed MCOA delineates the affected region through non-convex border extraction and edge detection. An accuracy of 85% was obtained in the detection of melanoma using MCOA, when compared to traditional algorithms.Keywords
